Abstract (en)
[origin: US2008249345A1] A process of producing PX comprising providing a C<SUB>8</SUB>+ feedstock, the C<SUB>8</SUB>+ feedstock has C<SUB>8 </SUB>hydrocarbons and C<SUB>9</SUB>+ hydrocarbons, to a crystallization unit under crystallization conditions to produce a PX enriched stream having a PX concentration of at least 99.5 wt % based on the weight of the PX enriched stream, wherein the C<SUB>8</SUB>+ feedstock has a PX concentration of at least 70 wt % based on total weight of xylenes in the C<SUB>8</SUB>+ feedstock, which the C<SUB>8</SUB>+ feedstock having a C<SUB>9</SUB>+ hydrocarbons concentration in a range from 1 wppm to 10 wt % based on the total weight of the C<SUB>8</SUB>+ feedstock.
